DETAILED DESCRIPTION

Embodiments of the present disclosure are described in detail hereafterwith reference to the accompanying drawings, to ensure that the objects,technical solutions, and advantages of the present disclosure are clear.

Liquid crystal molecules in a liquid crystal display device generallyhave elliptical or rodlike structures, a difference of electrondensities in a major-axis direction and a minor-axis direction resultsin birefringence, and light rays emitted along a direction parallel tothe major-axis and light rays emitted along a direction parallel to theminor-axis have different optical path differences, thereby resulting ina color shift and a gray-scale inversion.

A one-domain technology and a two-domain technology are two liquidcrystal display technologies. A liquid crystal display device employingthe one-domain technology includes sub-pixels with one-domainstructures, and FIG. 1 is a schematic diagram of a deflection of liquidcrystal molecules in the one-domain technology. As shown in FIG. 1 , inthe liquid crystal display device with the one-domain structure, theliquid crystal molecules in one sub-pixel region have a sameorientation. Dotted lines indicate an initial alignment direction of theliquid crystal molecules, and turning arrows indicate the deflectiondirection of the liquid crystal molecules. For a single alignmentdirection and a single electric field direction, the one-domainstructure has a single liquid crystal deflection direction, resulting indifferences in gray-scale or color in four directions A, B, C, and D inhuman eyes and causing a color shift.

In comparison with the one-domain technology, the two-domain technologyis beneficial to improve the display effect of the liquid crystaldisplay device and reduce problems such as the color shift, and thus inthe related art, the liquid crystal display device usually adoptssub-pixels with two-domain structures. FIG. 2 is a schematic diagram ofa deflection of liquid crystal molecules in the two-domain technology.As shown in FIG. 2 , in the liquid crystal display device with atwo-domain structure, one sub-pixel includes two parts, and for a singlealignment direction and two electric field directions, the liquidcrystal molecules in the two parts symmetrically deflect up and down andright and left, to realize complementation between the up and downdeflection and complementation between the left and right deflection toreduce the differences in gray-scale or color in the four directions A,B, C, and D.

FIG. 3 is a top view of an array substrate in the related art. The arraysubstrate is an array substrate of the liquid crystal display deviceemploying the two-domain technology. As shown in FIG. 3 , the arraysubstrate 100 includes a first substrate 10 and a conductive patternformed on the first substrate 10.

As shown in FIG. 3 , the conductive pattern includes a plurality of gatelines 11, a plurality of data lines 12, a plurality of pixel electrodes13, a common electrode 14, and a plurality of auxiliary commonelectrodes 15. The plurality of gate lines 11 and the plurality ofauxiliary common electrodes 15 are alternately disposed in parallel onthe first substrate 10, and the gate lines 11 and the auxiliary commonelectrodes 15 are made of a same layer of material, and generally may bemade of a same layer of metal material through a patterning process. Theplurality of gate lines 11 and the plurality of data lines 12 define aplurality of sub-pixel regions 100 a by crossing on the first substrate10, wherein the pixel electrodes 13 are disposed in the sub-pixelregions 100 a, and the pixel electrodes 13 are connected to the datalines 12 via thin film transistors 19 (as shown by elliptical dashedboxes in FIG. 3 ). The common electrode 14 is a surface electrode and isdisposed on a layer where the gate lines 11 and the auxiliary commonelectrodes 15 are disposed and a layer where the pixel electrodes 13 aredisposed. In order to facilitate viewing the common electrode 14, onepixel electrode 13 at an upper right corner is removed in FIG. 3 . Thecommon electrode 14 is connected to the auxiliary common electrodes 15via a plurality of via holes 16. An electric field for deflecting theliquid crystal molecules is formed between the pixel electrodes 13 andthe common electrode 14 upon powering up.

Taking an extending direction of the gate lines 11 as a row directionand an extending direction of the data lines 12 as a column direction,the auxiliary common electrodes 15 extend in the row direction, and eachauxiliary common electrode 15 is connected to the common electrode 14via a plurality of spaced via holes 16 to form a matrix common electrode(Matrix Vcom).

FIG. 4 is a schematic structural view of a color filter substrate in therelated art. The color filter substrate 200 is configured to cooperatewith the array substrate 100 shown in FIG. 3 when forming a displaypanel. As shown in FIG. 4 , the color filter substrate 200 includes asecond substrate 20 and a black matrix pattern, wherein the black matrixpattern includes a body 201. The body 201 defines a plurality ofsub-pixel regions 200 a on the second substrate 20. When manufacturingthe display panel, the sub-pixel regions 200 a on the color filtersubstrate 200 are one-to-one corresponding to the sub-pixel regions 100a on the array substrate 100.

Because the auxiliary common electrodes 15 are connected to the commonelectrode 14 via the via holes 16, in order to shield the regions of thevia holes 16, as shown in FIG. 4 , the black matrix pattern furtherincludes via hole shielding parts 202. The via hole shielding parts 202are disposed within the sub-pixel regions 200 a on the color filtersubstrate 200 and connected to the body 201 to form a whole. Whenarranging the color filter substrate 200 and the array substrate 100oppositely, orthographic projections of the via hole shielding parts 202on the array substrate 100 cover the via holes 16, so as to shield thevia holes 16.

Taking the color filter substrate 200 shown in FIG. 4 as an example,FIG. 5 is a schematic diagram of a sub-pixel region in FIG. 4 . Theregion defined by a dotted line in FIG. 5 is the sub-pixel region. Asshown in FIG. 5 , the sub-pixel region 200 a on the color filtersubstrate 200 includes a first domain 20 a and a second domain 20 b,wherein the first domain 20 a and the second domain 20 b are two regionsin the sub-pixel region 200 a of the color filter substrate 200 thatrespectively correspond to two parts in a sub-pixel with a two-domainstructure. In a same sub-pixel region 200 a, the first domain 20 a andthe second domain 20 b are arranged in the column direction, and the viahole shielding part 202 is disposed within the first domain 20 a. Theaperture ratio of the first domain 20 a and the aperture ratio of thesecond domain 20 b are generally equal or approximately equal. Theaperture ratio herein refers to a ratio of an area of alight-transmittable region to a total area, for example, the apertureratio of the first domain 20 a refers to a ratio of an area of alight-transmittable region of the first domain 20 a to the total area ofthe first domain 20 a. Because the via hole shielding part 202 is notpenetrable by light, the area of the light-transmittable region of thefirst domain 20 a is reduced due to the via hole shielding part 202, butthe total area of the first domain 20 a is unchanged. Therefore, in thesub-pixel region 200 a where the via hole shielding part 202 isdisposed, the aperture ratio of the first domain 20 a is reduced, suchthat a large difference occurs between the aperture ratio of the firstdomain 20 a and the aperture ratio of the second domain 20 b, which maycause a color shift problem and affect the display effect.

As shown in FIG. 5 , in order to reduce the aperture ratio of the seconddomain 20 b of the sub-pixel region 200 a where the via hole shieldingpart 202 is disposed, so as to return the aperture ratio of the firstdomain 20 a and the aperture ratio of the second domain 20 b in thesub-pixel region 200 a where the via hole shielding part 202 is disposedto be equal or similar, the black matrix pattern further includescompensation shielding parts 203. The compensation shielding parts 203are disposed within the second domains 20 b of the sub-pixel regions 200a where the via hole shielding parts 202 are disposed.

Because the compensation shielding parts 203 are opaque, thecompensation shielding parts 203 may reduce the areas of thelight-transmittable regions of the second domains 20 b. However, thetotal areas of the second domains 20 b are constant, such that theaperture ratios of the second domains 20 b of the sub-pixel regions 200a where the via hole shielding parts 202 are disposed are reduced due tothe existence of the compensation shielding parts 203. By adjusting thesizes of the compensation shielding parts 203, the aperture ratios ofthe first domains 20 a and the aperture ratios of the second domains 20b in the sub-pixel regions 200 a where the via hole shielding parts 202are disposed can be restored to be equal or similar, such that the colorshift may be reduced. However, the arrangement of the compensationshielding parts 203 further reduces the aperture ratios of the sub-pixelregions 200 a where the via hole shielding parts 202 are disposed,namely the ratios of the areas of the light-transmittable regions of thesub-pixel regions 200 a to the total areas of the sub-pixel regions 200a, such that differences between the aperture ratios of the sub-pixelregions 200 a where the via hole shielding parts 202 are disposed andaperture ratios of the other sub-pixel regions 200 a become evengreater, which may cause horizontal stripes on the liquid crystaldisplay device and affect the display effect.

An embodiment of the present disclosure provides a schematic structuraldiagram of a display panel. The display panel includes an arraysubstrate 100 and a color filter substrate 200 that are oppositelyarranged. FIG. 6 is a top view of the display panel according to theembodiment of the present disclosure. The array substrate 100 is underthe color filter substrate 200 shown in FIG. 6 . As shown in FIG. 6 ,the color filter substrate 200 includes a second substrate 20 and ablack matrix pattern, wherein the black matrix pattern includes a body201, via hole shielding parts 204, and compensation shielding parts 205,both the hole shielding part 204 and the compensation shielding part 205being connected to the body 201.

The body 201 defines a plurality of sub-pixel regions 200 a arranged inan array on the second substrate 202. FIG. 7 is a partially enlargedschematic diagram of FIG. 6 . As shown in FIG. 7 , each sub-pixel region200 a includes a first domain 20 a and a second domain 20 b. The firstdomains 20 a alternate with the second domains 20 b in a first directionin which the first domain 20 a and the second domain 20 b in a samesub-pixel region are arranged.

As shown in FIG. 7 , in a second direction, the first domains 20 a indifferent sub-pixel regions are adjacent, the second domains 20 b indifferent sub-pixel regions are adjacent, wherein the second directionis intersected with the first direction.

Illustratively, the first direction herein may be a column direction inwhich the sub-pixel regions 200 a are arranged, i.e., an X directionshown in FIG. 7 , and the second direction may be a row direction inwhich the sub-pixel regions 200 a are arranged, i.e., a Y directionshown in FIG. 7 , wherein the first direction and the second directionmay be parallel to boundaries of the second substrate 20.

The via hole shielding parts 204 are disposed within the first domains20 a of part of the plurality of sub-pixel regions 200 a. The via holeshielding parts 204 are configured to shield the via holes (referring tothe via holes 16 shown in FIG. 3 ) for connecting the common electrodeto the auxiliary common electrodes in the case that the color filtersubstrate 200 is assembled with the array substrate 100.

The compensation shielding parts 205 are disposed within the seconddomains 20 b that are adjacent in the first direction to the firstdomains 20 a where the via hole shielding parts 204 are disposed, and atmost one of the via hole shielding part 204 and the compensationshielding part 205 is disposed in one sub-pixel region 200 a.

FIG. 8 is a cross-sectional view along C-C in FIG. 7 . As shown in FIG.8 , the array substrate 100 includes a first substrate 10, a commonelectrode 14, a plurality of auxiliary common electrodes 15, and a firstinsulating layer 17. The plurality of auxiliary common electrodes 15 arespaced on the first substrate 10, the first insulating layer 17 isdisposed on the plurality of auxiliary common electrodes 15, and thecommon electrode 14 is disposed on the first insulating layer 17. Thefirst insulating layer 17 is provided with via holes 16, the auxiliarycommon electrodes 15 are connected to the common electrode 14 via thevia holes 16, and orthographic projections of the via holes 16 on thefirst substrate 10 are within orthographic projections of the via holeshielding parts 204 on the first substrate 10.

A minimum distance d between edges of the orthographic projections ofthe via holes 16 on the first substrate 10 and edges of the orthographicprojections of the via hole shielding parts 204 on the first substrate10 ranges from 3.5 to 6 microns, so as to ensure that the via holeshielding parts 204 can shield the via holes 16 to avoid light leakage,and at the same time ensure that corresponding sub-pixels haveappropriate aperture ratios.

The common electrode 14 is further provided with a plurality of throughholes 14 a, wherein via holes for connecting to the pixel electrodes 13are formed in the through holes 14 a, and thin film transistors 19 areconnected to the pixel electrodes 13 via the via holes for connecting tothe pixel electrodes 13.

The array substrate 100 is an array substrate with a matrix commonelectrode. For example, the array substrate 100 may be the arraysubstrate shown in FIG. 3 . FIG. 9 is a cross-sectional view along A-Ain FIG. 3 . The thin film transistors 19 connecting the pixel electrodes13 and the data lines 12 are omitted in FIG. 9 . Referring to FIG. 3 andFIG. 9 , the plurality of gate lines 11 and the plurality of data lines12 define a plurality of sub-pixel regions 100 a by crossing on thefirst substrate 10. The plurality of gate lines 11 and the plurality ofauxiliary common electrodes 15 are alternately spaced on the firstsubstrate 10. The plurality of gate lines 11 and the plurality ofauxiliary common electrodes 15 are covered with the first insulatinglayer 17, the plurality of pixel electrodes 13 are arranged in an arrayon the first insulating layer 17, each sub-pixel region 100 a isprovided with one pixel electrode 13, the plurality of pixel electrodes13 are covered with a second insulating layer 18, the common electrode14 is disposed on the second insulating layer 18, and the commonelectrode 14 is connected to the auxiliary common electrodes 15 via thevia holes 16.

The via hole shielding parts and the compensation shielding parts areprovided, wherein the via hole shielding parts are configured to shieldthe via holes for connecting the common electrode to the auxiliarycommon electrodes and may reduce the aperture ratios of the firstdomains of the sub-pixel regions where the via hole shielding parts aredisposed, and the compensation shielding parts reduce the apertureratios of the second domains of the sub-pixel regions where thecompensation shielding parts are disposed. In a sub-pixel region wherethe via hole shielding part or the compensation shielding part isdisposed, the aperture ratios of the first domain and the second domainof the same sub-pixel region are not equal. However, regarding asub-pixel region where the via hole shielding part is disposed and anadjacent sub-pixel region thereof in the first direction where thecompensation shielding part is disposed as a whole and as a largersub-pixel region, the two sub-pixel regions are equivalent to twodomains of the larger sub-pixel region, wherein one of the two domainsincludes the via hole shielding part, and the other domain includes thecompensation shielding part, that is, each of the two domains isaffected by one of the shielding parts. Therefore, a difference ofaperture ratios of the two domains of the larger sub-pixel region issmall, and the color shift of the display device can be reduced.Moreover, at most one of the via hole shielding part and thecompensation shielding part is disposed in one sub-pixel region, suchthat the difference between the aperture ratio of the sub-pixel regionwhere the via hole shielding part or the compensation shielding part isdisposed and the aperture ratio of the sub-pixel region where neitherthe via hole shielding part nor the compensation shielding part isdisposed is affected by only one of the shielding parts, which isbeneficial to reduce the difference in aperture ratio between differentsub-pixel regions, weaken horizontal stripes appearing in the liquidcrystal display device, and improve the display effect. Moreover, theeffect can be improved only by changing the black matrix pattern withoutaffecting other processes, and the cost is low.

Optionally, both the first substrate 10 and the second substrate 20 areglass substrates, plastic substrates, or quartz substrates. The glasssubstrates, plastic substrates, or quartz substrates have bettertransparency.

Optionally, the black matrix pattern is made of a black resin material.

As shown in FIG. 6 , the via hole shielding parts 204 that are adjacentin the first direction are spaced by one sub-pixel region 200 a.

As described above, the distribution of the sub-pixel regions 200 a onthe color filter substrate 200 corresponds to the distribution of thesub-pixel regions 100 a on the array substrate. In the case that the viahole shielding parts 204 that are adjacent in the first direction on thecolor filter substrate 200 are spaced by one sub-pixel region 200 a, thesub-pixel regions 100 a that are provided with the via holes 16 andadjacent in the same direction on the array substrate corresponding tothe color filter substrate 200 are spaced by one sub-pixel region 100 a.The more the sub-pixel regions 100 a are disposed between the adjacentsub-pixel regions 100 a that are provided with the via holes 16, themore sparsely the via hole shielding parts 204 are distributed in thefirst direction, the harder the via hole shielding parts 204 are to beperceived during the display of a picture by the display panel, and theless the display effect is affected. Therefore, the via hole shieldingparts 204 that are adjacent in the first direction are spaced by atleast one sub-pixel region 200 a.

As shown in FIG. 6 , the via hole shielding parts 204 that are adjacentin the second direction are spaced by five sub-pixel regions 200 a.

In the second direction, in the case that the via hole shielding parts204 are arranged too densely, that is, the adjacent via hole shieldingparts 204 are spaced by fewer or even zero sub-pixel region 200 a, theplurality of via shielding parts 204 and the plurality of compensationshielding parts 205 in the same row in the second direction may form alarge shielding area, which may be so visually obvious that the displayeffect is influenced. By spacing the adjacent via hole shielding parts204 with a specific number of sub-pixel regions 200 a, this influencecan be reduced and the display effect can be improved.

Optionally, the via hole shielding parts 204 that are adjacent in thesecond direction are spaced by 2-5 sub-pixel regions 200 a. For thematrix common electrode, in the row direction, one via hole 16 isgenerally disposed every 2 or 5 sub-pixel units 200 a to connect theauxiliary common electrodes 15 to the common electrodes 14; and thenumber of the sub-pixel regions 200 a disposed between the adjacent viahole shielding parts 204 in the color filter substrate 200 in the seconddirection may be determined depending on the matrix common electrode onthe array substrate.

Optionally, the via hole shielding parts 204 that are adjacent to eachother in the second direction are spaced by an odd number of sub-pixelregions 200 a, wherein the compensation shielding part 205 is disposedin a middle sub-pixel region among the odd number of sub-pixel regions200 a. For example, in the embodiment, the via hole shielding parts 204that are adjacent to each other in the second direction are spaced by 5sub-pixel regions 200 a, and the compensation shielding part 205 isdisposed in the middle sub-pixel region among the 5 sub-pixel regions200 a. The via hole shielding parts 204 and the compensation shieldingparts 205 are staggered in the second direction and are distributed moreuniformly on the whole, and a viewer is less likely to perceive thepresence of the via hole shielding parts 204 and the compensationshielding parts 205, such that the whole display effect of the liquidcrystal display device is less affected.

As shown in FIG. 7 , a boundary region between two adjacent sub-pixelregions 200 a in the first direction includes a first boundary region2001, and a boundary region between two adjacent sub-pixel regions 200 ain the second direction includes a second boundary region 2002. Thefirst boundary regions 2001 are intersected with the second boundaryregions 2002. The first boundary region 2001 and the second boundaryregion 2002 are both a part of the body 201.

Optionally, the via hole shielding parts 204 are disposed at corners ofthe sub-pixel regions 200 a, i.e., at corners formed by the firstboundaries 2001 and the second boundaries 2002. On the array substrate100, the sub-pixel regions 100 a are generally shaped like a roughpolygon, and the via holes 16 are generally disposed at corners of thesub-pixel regions 100 a to reduce the influence on the aperture ratios.On the color filter substrate 200, the via hole shielding parts 204 aredisposed at the corners of the sub-pixel regions 200 a to correspond topositions of the via holes 16, so as to provide good shielding for theregions where the via holes 16 are disposed.

Illustratively, the via hole shielding parts 204 are rectangular. Thevia hole shielding parts 204 may have other shapes, such as asemicircular shape, and the shapes and sizes of the via hole shieldingparts 204 may be set according to the shapes and sizes of the regions tobe shielded. On the condition that the via holes 16 can be shielded,minimizing the sizes of the via hole shielding parts 204 can facilitateincreasing the aperture ratios of the sub-pixel regions 200 a andimproving the luminance of the liquid crystal display device.

Optionally, the compensation shielding part 205 is disposed near theboundary region between two adjacent sub-pixel regions 200 a in thefirst direction. As shown in FIG. 7 , the compensation shielding part205 is connected to the first boundary region 2001.

The sizes of the compensation shielding parts 205 and the via holeshielding parts 204 may be equal, such that the influence of thecompensation shielding parts 205 on the aperture ratios of the seconddomains 20 b is equal to the influence of the via shielding parts 204 onthe aperture ratios of the first domains 20 a.

As shown in FIG. 7 , the boundary line of the second domain 20 b wherethe compensation shielding part 205 is disposed is a straight line.Comparing the second domains 20 b where the compensation shielding part205 is disposed and the second domains 20 b of other sub-pixel regions,the boundaries of the second domains 20 b of the other sub-pixel regions200 a are not straight lines, this is because the array substratefurther includes structures such as thin film transistors, and in orderto shield the structures such as the thin film transistors, the boundaryline of the second domain 20 b is partially concave and partiallyconvex, thereby presenting a concave-convex shape. In the second domainwhere the compensation shielding part 205 is disposed, the compensationshielding part 205 fills the concave-convex shape of the boundary lineof the second domain 20 b, making the boundary line of the second domain20 b straight. The straight boundary line is easier to form during apatterning process. The boundary line of the second domain 20 b wherethe compensation shielding part 205 is disposed may be parallel to oneedge of the second substrate 20.

Optionally, the aperture ratios of the sub-pixel regions 200 a where thevia hole shielding parts 204 are disposed are equal to the apertureratios of the sub-pixel regions 200 a where the compensation shieldingparts 205 are disposed. The sub-pixel region 200 a where the via holeshielding part 204 is disposed is adjacent to the sub-pixel region 200 awhere the compensation shielding part 205 is disposed. In the case thatthe sub-pixel region 200 a where the via hole shielding part 204 isdisposed and the sub-pixel region 200 a where the compensation shieldingpart 205 is disposed are regarded as a whole and considered as a largersub-pixel region, the sub-pixel region 200 a where the via holeshielding part 204 is disposed and the sub-pixel region 200 a where thecompensation shielding part 205 is disposed are respectively two domainsof the larger sub-pixel region, and the aperture ratio of the sub-pixelregion 200 a where the via hole shielding part 204 is disposed is equalto the aperture ratio of the sub-pixel region 200 a where thecompensation shielding part 205 is disposed, that is, the apertureratios of the two domains of the larger sub-pixel region are equal,which is beneficial to reduce the color shift of the liquid crystaldisplay device.

Optionally, a difference of the aperture ratios of any two sub-pixelregions 200 a does not exceed 3%. Due to the influences of the via holeshielding parts 204 and the compensation shielding parts 205 on theaperture ratios, both the aperture ratio of the sub-pixel region 200 awhere the via hole shielding part 204 is disposed and the aperture ratioof the sub-pixel region 200 a where the compensation shielding part 205is disposed are smaller than the aperture ratios of the other sub-pixelregions 200 a. For example, in FIG. 7 , both the aperture ratios of thetwo sub-pixel regions 20 a in the second column are smaller than theaperture ratios of the other sub-pixel regions 20 a.

In the crystal display device, the difference in aperture ratio betweendifferent sub-pixel regions 200 a may cause horizontal stripes in adisplayed picture, and the greater the difference is, the more obviousthe horizontal stripes are. Generally, in the case that the differencein aperture ratio reaches 3%, obvious horizontal stripes may appear onthe picture. Controlling the difference in aperture ratio between theplurality of sub-pixel regions 200 a to not exceed 3% can facilitatereducing or weakening the horizontal stripes in the displayed pictureand improving the display effect.

Optionally, the sub-pixel regions 200 a where the via hole shieldingparts 204 are disposed are blue sub-pixel regions. In the arraysubstrate 100, there are generally red sub-pixel regions, greensub-pixel regions, and blue sub-pixel regions. The via holes 16 forconnecting the common electrode 14 and the auxiliary common electrodes15 are generally disposed within the blue sub-pixel regions, and thesub-pixel regions 200 a where the via hole shielding parts 204 aredisposed are blue sub-pixel regions, such that in the case that thearray substrate 100 is oppositely arranged to the color filter substrate200, the via hole shielding parts 204 may just shield the via holes 16in the blue sub-pixel regions. For the array substrate 100 with the viaholes 16 in the red sub-pixel regions or the green sub-pixel regions,the sub-pixel regions 200 a where the via hole shielding parts 204 aredisposed are also correspondingly red sub-pixel regions or greensub-pixel regions.

An embodiment of the present disclosure further provides a displaydevice. The display device is any product or component with a displayfunction, such as a mobile phone, a tablet computer, a television, amonitor, a notebook computer, a digital photo frame, or a navigator. Thedisplay device includes the above-described display panel.

FIG. 10 is a flowchart of a method for manufacturing a display panelaccording to an embodiment of the present disclosure. The method is usedfor manufacturing the display panel shown in FIG. 6 . As shown in FIG.10 , the method includes the following processes.

In process S11, an array substrate and a color filter substrate areprovided.

The array substrate includes a first substrate, a common electrode, aplurality of auxiliary common electrodes, and a first insulating layer,wherein the plurality of auxiliary common electrodes are spaced on thefirst substrate, the first insulating layer is disposed on the pluralityof auxiliary common electrodes, the common electrode is disposed on thefirst insulating layer, the first insulating layer is provided with viaholes, and the auxiliary common electrodes are connected to the commonelectrode via the via holes. The color filter substrate includes asecond substrate and a black matrix pattern, wherein the black matrixpattern includes a body, via hole shielding parts, and compensationshielding parts, both the hole shielding part and the compensationshielding part being connected to the body. The body defines a pluralityof sub-pixel regions arranged in an array on the second substrate,wherein each sub-pixel region includes a first domain and a seconddomain, the first domains alternating with the second domains in a firstdirection in which the first domain and the second domain of a samesub-pixel region are arranged. The via hole shielding parts are disposedwithin the first domains of part of the plurality of sub-pixel regions,the compensation shielding parts are disposed within the second domainsthat are adjacent in the first direction to the first domains where thevia hole shielding parts are disposed, and at most one of the via holeshielding part and the compensation shielding part is disposed in onesub-pixel region.

Optionally, both the first substrate and the second substrate are glasssubstrates, plastic substrates, or quartz substrates. The glasssubstrates, plastic substrates, or quartz substrates have bettertransparency.

In a second direction, the first domains in different sub-pixel regionsare adjacent, and the second domains in different sub-pixel regions areadjacent, the second direction being intersected with the firstdirection.

Optionally, the black matrix pattern may be formed of a black resinmaterial on the second substrate through a patterning process. Forexample, first, a layer of black resin film is formed on the secondsubstrate, and then the black resin film is processed through thepatterning process to form the black matrix pattern.

In process S12, the color filter substrate and the array substrate arearranged oppositely to cause orthographic projections of the via holeson the first substrate to be within orthographic projections of the viahole shielding parts on the first substrate.

The via hole shielding parts and the compensation shielding parts areprovided, wherein the via hole shielding parts are configured to shieldthe via holes for connecting the common electrode to the auxiliarycommon electrodes and may reduce the aperture ratios of the firstdomains of the sub-pixel regions where the via hole shielding parts aredisposed, and the compensation shielding parts reduce the apertureratios of the second domains of the sub-pixel regions where thecompensation shielding parts are disposed. In a sub-pixel region wherethe via hole shielding part or the compensation shielding part isdisposed, the aperture ratios of the first domain and the second domainof the same sub-pixel region are not equal. However, regarding asub-pixel region where the via hole shielding part is disposed and anadjacent sub-pixel region thereof in the first direction where thecompensation shielding part is disposed as a whole and as a largersub-pixel region, the two sub-pixel regions are equivalent to twodomains of the larger sub-pixel region, wherein one of the two domainsincludes the via hole shielding part, and the other domain includes thecompensation shielding part, that is, each of the two domains isaffected by one of the shielding parts. Therefore, a difference ofaperture ratios of the two domains of the larger sub-pixel region issmall, and the color shift of the display device can be reduced.Moreover, at most one of the via hole shielding part and thecompensation shielding part is disposed in one sub-pixel region, suchthat the difference between the aperture ratio of the sub-pixel regionwhere the via hole shielding part or the compensation shielding part isdisposed and the aperture ratio of the sub-pixel region where neitherthe via hole shielding part nor the compensation shielding part isdisposed is affected by only one of the shielding parts, which isbeneficial to reduce the difference in aperture ratio between differentsub-pixel regions, weaken horizontal stripes appearing in the liquidcrystal display device, and improve the display effect.
